本章主要介绍了研究超导量子比特的汉密尔顿形式。第一部分分别讨论相位、电荷和磁通量子比特。为了实现基于JJ的量子比特操作及其应用，需要mK温区。从Chap开始。1，CPR的非谐特性在此温度下变得重要，因此在考虑JJ量子位时必须考虑非谐性。由于这个原因，非谐波CPR对量子比特特性的影响在第4.2节中给出。4.3节中给出了使用非谐CPR的沉默量子位的描述。基于第4.4节中分析的三个JJ的通量量子位。第4.5节专门讨论绝热测量，超导量子比特中的拉比振荡在第4.6节。
This chapter is devoted to describe Hamilton formalism for studying superconducting quantum bits (qubits). The first section is devoted to discuss phase, charge and flux qubits separately. For the realization of qubit operations based on JJ and their application requires the mK temperature regions. As followed from Chap. 1, anharmonic character of CPR becomes important at this temperatures and as result anharmonicity must be taken into account in consideration of JJ qubits. For this reason the influence of anharmonic CPR on qubit characteristics presented in Sect. 4.2. Description of silent qubit using anharmonic CPR given in Sect. 4.3. Flux qubit based on three JJ analyzed in Sect. 4.4. Section 4.5 is devoted to adiabatic measurements and Rabi oscillations in superconducting qubits is in Sect. 4.6.
